ʻO ka cellulose ether kahi non-ionic semi-synthetic high molecular polymer, ʻo ia ka wai-soluble a me ka solvent-soluble.Loaʻa nā hopena like ʻole i nā ʻoihana like ʻole.No ka laʻana, i nā mea hale kemika, loaʻa iā ia nā hopena composite penei:
①He mea mālama wai
②Ka mānoanoa
③Ka pae ʻana
④Hoʻokumu kiʻiʻoniʻoni
⑤ Mea hoʻopili
I ka ʻoihana polyvinyl chloride, he emulsifier a me ka dispersant;i loko o ka lāʻau lapaʻau, he mea hoʻopaʻa a me ka mea hoʻokuʻu lohi a hoʻokuʻu ʻia, a me nā mea ʻē aʻe.A laila, e nānā au i ka hoʻohana ʻana a me ka hana o ka cellulose ether i nā ʻano mea hale.
1. I ka pena latex
I ka ʻoihana pena latex, e koho i ka hydroxyethyl cellulose, ʻo ka kikoʻī maʻamau o ka viscosity like ʻo 30000-50000cps, e pili ana i ka kikoʻī HBR250, a ʻo ka helu kuhikuhi ma kahi o 1.5‰-2‰.ʻO ka hana nui o ka hydroxyethyl i ka pena latex ka mānoanoa, pale i ka gelation o ka puaʻa, kōkua i ka hoʻopuehu ʻana o ka puaʻa, ka paʻa o ka latex, a hoʻonui i ka viscosity o nā ʻāpana, e kōkua i ka hoʻonui ʻana i ka hana o ke kūkulu ʻana: ʻOi aku ka maʻalahi o ka hydroxyethyl cellulose e hoʻohana.Hiki ke hoʻoheheʻe ʻia i loko o ka wai anuanu a me ka wai wela, ʻaʻole pili i ka waiwai pH.Hiki ke hoʻohana pono ʻia ma waena o ka waiwai PI 2 a me 12. ʻO nā ʻano o ka hoʻohana ʻana penei:
I. Hoʻohui pololei i ka hana
No kēia ʻano, pono ke koho ʻia ka hydroxyethyl cellulose ʻano lohi, a hoʻohana ʻia ka hydroxyethyl cellulose me kahi manawa hoʻopau ʻoi aku ma mua o 30 mau minuke.Penei nā ʻanuʻu: ① E hoʻokomo i ka nui o ka wai maʻemaʻe i loko o kahi pahu i hoʻolako ʻia me kahi mea hoʻouluulu kiʻekiʻe ② E hoʻomaka i ka hoʻoulu ʻana me ka wikiwiki haʻahaʻa, a ma ka manawa like e hoʻohui mālie i ka hui hydroxyethyl i loko o ka hopena ③E hoʻomau i ka hoʻoulu ʻana a hiki i ka hoʻomoʻu ʻia nā mea granular a pau ④E hoʻohui i nā mea hoʻohui a me nā mea hoʻohui kumu, a me nā mea ʻē aʻe.
Ⅱ.Hoʻolako ʻia me ka waiʻona makuahine no ka hoʻohana ʻana ma hope
Hiki i kēia ʻano ke koho koke i ke ʻano, a he anti-mildew hopena cellulose.ʻO ka maikaʻi o kēia ʻano hana ʻoi aku ka maʻalahi a hiki ke hoʻohui pololei ʻia i ka pena latex.ʻO ke ʻano o ka hoʻomākaukau ʻana e like me nā ʻanuʻu ①-④.
Ⅲ.E hana i ka porridge no ka hoʻohana hope
No ka mea, ʻo nā mea hoʻoheheʻe organik he mau mea hoʻoheheʻe maikaʻi ʻole (inoluble) no ka hydroxyethyl, hiki ke hoʻohana ʻia kēia mau mea hoʻoheheʻe e hana i ka porridge.ʻO nā mea hoʻoheheʻe organik i hoʻohana pinepine ʻia he wai kūlohelohe i loko o nā hana pena latex, e like me ka ethylene glycol, propylene glycol, a me nā mea hana kiʻiʻoniʻoni (e like me diethylene glycol butyl acetate).Hiki ke hoʻohui pololei ʻia ka porridge hydroxyethyl cellulose i ka pena.E hoʻomau i ka hoʻouluʻana a hiki i ka hemo loa.
ʻO ka lua, ma ka pā ʻoki ʻana i ka putty
I kēia manawa, ma ka hapa nui o nā kūlanakauhale o koʻu ʻāina, ua waiwai nui ʻia e ka poʻe ka putty kūpaʻa i ka wai a me ka scrub-resistant environment-friendly putty.Hana ʻia ia e ka hopena acetal o ka waiʻona vinyl a me ka formaldehyde.No laila, hoʻopau mālie ʻia kēia mea e ka poʻe, a hoʻohana ʻia nā huahana cellulose ether series e pani i kēia mea.ʻO ia hoʻi, no ka hoʻomohala ʻana i nā mea hale e pili ana i ke kaiapuni, ʻo ka cellulose wale nō ka mea i kēia manawa.
I loko o ka putty wai-kūpaʻa, ua māhele ʻia i ʻelua ʻano: putty pauka maloʻo a me putty paste.Ma waena o kēia mau ʻano putty ʻelua, pono e koho ʻia ka methyl cellulose a me ka hydroxypropyl methyl.ʻO ka kikoʻī viscosity ma waena o 40000-75000cps.ʻO nā hana nui o ka cellulose ka mālama ʻana i ka wai, ka hoʻopaʻa ʻana a me ka lubrication.
No ka mea he ʻokoʻa nā ʻano putty o nā mea hana like ʻole, he calcium hina, calcium māmā, sima keʻokeʻo, a me nā mea ʻē aʻe, a ʻo kekahi he pauka gypsum, calcium hina, calcium māmā, etc., no laila nā kikoʻī, viscosity a me ke komo ʻana o ka cellulose i loko ʻokoʻa nō hoʻi nā papa ʻelua.ʻO ka nui i hoʻohui ʻia ma kahi o 2‰-3‰.
